Great White Shark Jumps Into Fisherman's Boat, Injuring 73-year-old Man
Introducing the ribbon worm, a member of the Nemertea phylum of primitive invertebrates that happens to include one of the longest-known animals on Earth. When the worm is hunting, however, that highly efficient, stretchy feeding tube will unfurl and emerge just above its mouth, to cover its prey in a thick, sticky, and slightly pungent mucus. All of which already sounds fairly unpleasant, but the worst part is that it contains a relatively strong neurotoxin that can paralyse small prey so they quit struggling. Which is exactly what the worm in the video above is trying to do to that man's hand. I guess extra points for the effort, right?
